I have one of each, a K3S with USB and a K3 without. When I was having FT8
problems (not sure they're over) I set up both radios and "worked myself". The
K3 was setup exactly as Jim describes, down to the same sound card, and the K3s
used the internal USB. It's much easier to set proper TX audio levels with the
external card, but that's a continuing gripe, not to be expanded on here.
I too use VOX but let the program set Split and Mode. (There is a timing issue
doing this; something I mentioned in another thread.) So after seeing that
someone else claimed to be using PTT via USB instead of VOX I attempted to use
it. I wound up getting hamlib errors and since I'm not so invested in this mode
anyway, went back to VOX, which is what I use for RTTY and PSK anyway.

To clarify my situation, I'm running a K3 with the new KIO3B with the integral
sound and USB interface, and it was running properly using WJST-X V1.7. The
Hamlib library problem that I encountered also affects certain Kenwood users as
well, and the development team is well aware of the issues. I have used an
external sound interface (Asus Xonar U5) in the past, but opted to simplify
things when the KIO3B became available.

FWIW, I and many others have been using the posted compiled version of
WSJT-X 1.8-rc1 from the official WSJT-X website with a K3, and without
problems. I'm not using a lot of "bells and whistles" -- I'm using a
vintage K3 with an outboard USB to serial converter from computer to
rig, a Tascam US100 USB audio interface for the computer, and VOX with
the K3 in DATA A mode. I'm doing almost no rig control -- all the USB to
serial interface is doing is read and control frequency. On the <Radio>
tab of <Settings> select the K3 under Rig, set the serial port that the
computer has assigned to your USB to serial converter, set PTT method to
VOX, set Mode to None, and set Split Operation to None.
The Tascam US100 is simply a very good vintage USB to analog stereo
audio I/O designed for home semi-pro recording studios. There's lots of
comparable stuff that works. It ONLY handles audio, no control functions.
